答案 0 :(得分：1)
好的，问题是condition是 MySQL中的保留字，您可以在here中获取详细信息（或者您可以从网站获取其他文档版本）。
根据经验，如果你得到org.hibernate.exception.SQLGrammarException，有时候是由于保留字问题。
另一个提示是建议显示sql并尝试直接在数据库中运行sql，它会更容易找到sql问题。
您可以在spring boot中使用spring.jpa.show-sql=true来显示hibernate sql。
答案 1 :(得分：0)
条件是MySQL中的保留字，因此是错误。
在您的应用程序模型中将变量Condition更改为shipCondtion。
我认为你也会创建一个flyway迁移脚本：
create table shipwreck(
`id` int(10) NOT NULL AUTO_INCREMENT,
`name` varchar(255),
`description` varchar(255),
`ship_condition` varchar(255),
`depth` int(10),
`latitude` double(17,4),
`longitude` double(17,4),
`year_discovered` int(4),
PRIMARY KEY(id)
);
现在应该可以正常工作了。
您不需要在application.properties中定义MySQLDialect：
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
